This week I tried to reboot the server and in the process I checked the boot process in the IPMI remote console. The system only showed the unRAID boot selection and nothing else. No Supermicro splash screen or the typical loading information of unRAID. That also means, I can't use IPMI to use the unRAID console directly. I did a reset of the BIOS/BMC, but nothing changed. I also haven't changed the settings in the BIOS the last few month. IGFX is activated for the iGPU but not really more. Somebody on Reddit guessed that the graphical output might be redirected to the iGPU.

I can get into the BIOS and I can see the output, but nothing else except the unRAID boot selection.

FW MB: 5.1

FW BMC: 01.04.15

Question:

Has somebody discovered something like this and know how to solve this?

Is it the same if you use Java to access BMC output?

Hm...how can I use it with a Mac?

Oh...

GitHub

GitHub - TheCase/IPMIView.app: MacOS App wrapper for Supe...

MacOS App wrapper for Supermicro's IPMIView/iKVM java app - TheCase/IPMIView.app

will try.

That doesn't run on my M2 Mac with MacOS 26. I can start the app but the console will not fire up...(I get JAVA errors).

That package isn't enough...you need the full JDK.

Does it show anything else after a reboot or fresh boot? Unraid cannot redirect anything until it loads the drivers.

It's not a Java viewer, that's for much old boards... it'll be HTML5 and not have any prerequisites for you to use

I have powered the server down and started through IPMI again. The first thing I see is the blue unRAID box, where I can choose what to start. Nothing before it nothing after it.

I can't try a full shutdown (power supply off) at the moment. I can do that later this week.

What's also interesting. The FPS output in the top of the console window is jumping around even when the screen is black.

You mean this one?

It just opens the console window in a browser. So...the same when I use the browser to access the IPMI itself....

That suggests to me Unraid is not the issue, you should see the IPMI initialization and BIOS during post. Recommend opening a support ticket with Supermicro.

BIOS:

INTERNAL GRAPHICS can't be set to 'Auto'. It needs to be disabled.
